INSOLE Filed April 4, 1931 Patented Apr. 4, 1933 UNITED STATES .mxon nnonn, or MUNICH, GERMANY INSOLE Application filed April 4, 1931 Serial No. 527,741, and in Germany February 26, 1931.

This invention relates to an insole, chiefly for feet, which are not orthopedically perfectly formed, and presents the advantage that therein neither metal nor rivets, which 5 show through, when the insole is being worn,

nor rubber, which makes the foot unnecessarily hot, is employed.

According to the invention the insole consists of a leather sole cut to the desired shape and pressed to the required curvature, on which a piece of plaited gut strings is insert ed so that a hollow space is formed between this piece and the sole. This hollow space is reduced when the insole is loaded by the relieved.

Such an insole can according to the way in which it is made be employed for all kinds of deformed feet, for example flat feet, hollow insteps, weak insteps, splay feet and the like. As compared with the known insoles it possesses the advantage that the hollow of the foot does not rest on a rigid support, but that this support is resilient so that the foot can easily carry out a. rolling movement in forward direction.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which Fig. 1 shows a right hand insole in bottom plan view. v

Fig. 2 is a longitudinal section of Fig. 1.

Fig. 3 is a perspective view of Fig. 1.

Fig. 4: shows how such an insole must be made for example for splay feet.

Fig. 5 shows an insole made for a hollow instep.

a designates the suitably pressed and cut leather piece, I) designates the longitudinal staying by means of gut strings, 0 the transverse staying and d the known lateral support of the insole.

The section Fig. 4 taken on line mw of Fig. 3 shows how such an insole must be made for splay feet so that a pad or raised portion h, which bears under the small ball, can be applied, whereas a further padding or raised portion g is assumed for the lateral correction of the foot.

In Fig. 5 i designates the depression for foot and again enlarges when the insole is the heel and k the depression for the large toe ball in insoles for hollow insteps.

The under side ofthe gut stringing may evidently also be covered with a cover 7, and the insole may have a cover e on the bottom and on the top. Consequently, as may be seen, the insole can be constructed for any deformed foot, the stringing being increased at points, which are heavily loaded and reduced at points, which are less heavily load ed. Such an insole is comfortable and preyents foot diseases also in the case of healthy eet.

I claim 1. An insole for feet to be orthopedically treated, comprising in combination a piece of leather out to size and curved like an insole, and an element composed of longitudinal and transverse gut strings stretched on the concave side of said piece of leather, connected at their ends directly to said piece of leather and interconnected at their points of intersection and adapted to limit the de pressing of the curved portion of the insole and to return said piece of leather into its initial curved shape when the insole is not loaded.

2. An insole as specified in claim 1, in which both the longitudinal and the transverse gut string stayings are closer spaced at points so subject to heavy load than at points less heavily loaded.

3. An insole as specified in claim 1, in which the piece of leather has depressions and raised portions for the deformed points and for correcting same.

In testimony whereof I affix my signature.
